PORTLAND, Ore. (AP) — Two Oregon residents have sued a health care provider that screened them for HIV without their permission.

The Oregonian reports (http://is.gd/YM3CDa ) the plaintiffs are asking the judge to approve the suit as a class action, to include the estimated 6,500 other people who were tested by Kaiser Permanente without permission.

Oregon law requires companies to inform patients they are about to be tested for the virus, and give them the opportunity to decline testing.

But Kaiser tested Oregon and Washington members ages 50 to 65 from April 11 to May 5, but didn’t tell them what they were up to.
